The Schedule referred to in these Letters Patent and making part or" thesame.

To all whom it may concern Be it known that we, RICHARD Human and JAMESB. HOLDEN,-b0iih of Jersey City, in the county of Hudson and State ofNew Jersey, have invented new and useful Improvements in Mechanism forTransmitting IoWen-anjd increasing the effects of the same; and we ,dohereby declare that the followmg is a full and exact-descriptionthereof, reference being had to the accompanying drawings forming a partof this specification, and to the letters of referry, it forms-a mosteflective machine for hoisting, pressing, and other purposes.

The nature of this invention consists in the use or employment ofanindcpendent intermediate wheel, weighted or loaded as hereinafter moreparticularly described, thatis, supported on the inner surface of theiim of an outer annular'wheel, and drives the same, whiclrsaidintermediate wheel is driven by means of. a pinion fixed on a shaft thatruns within the hollow shafts of the outerwheel, and has-bearingstherein.

The said intermediate wheel is weighted or loaded proportionately to theamount of driving-power applied to the said pinion and the amount ofresistance to be overcome by the outer wheel, and to such an extentthat, while in operation, it will retain a position nearly perpendicularto or nearly directly un er the pinion before mentioned.

The driving-power is applied to the pinion, which imparts-a rollingmotion to the loaded intermediate wheel, upward upon the inner peripheryof the outer wheel, thus bringing the said-intermediate wheel into aposition in which the weight of the same operates in driving the outerwheel. v

i To enable others skilled in'the artto make and use our invention, wewill, now proceed more particularly to describe its construction andoperation,

Figure 1 represents a side elevation of our-improved mechanism;

(liigure 2 is a transverse vertical-section of the same an Figure 3 is acorresponding longitudinal vertical section.

, Letters 0! like name and kind indicate like'parts in each ofthefigures.

A is the outer annular wheel;

Bis the independent intermediate wheel; and" O is the pinion-wheel.

The outer wheel A is made of such dimensions and strength as may be mostsuitable for the ,amount of power to be applied thereto, and is providedwith any convenient number of arms, a a a a, one end of each of thesearms being bolted or otherwise secured to the'riin b, and the otherend'secured in any suitable manner to one of the hubs c c, which carrythe shafts D D of this wheel A. I

These shafts D D have Suitable bearings in the pillow-blocks H H,secured to and'supportedby any suitable frame, E.

The shafts D D are made hollow or cylindrical, for

the purpose of receiving the shaft F of the pinion,

which has bearings aud'runs within the same.

The independent intermediate wheel B ismade in the form of a boxed orflanged, gear-wheel, and it is supported on the inner surface of the rim7) of the outer whee], its flanges d (1 being in contact with the .plaininner surface of the rim 1), and causing friction thereon, by means ofwhich it drives the outer wheelA. This intermediate wheel B gears withthe pinion (l, which drives the same, and is weighted or loaded proportionately to the driving-power applied and the resistance to beovercome.

' The loading f may be secured to the wheel B in any convenient andsuitable manner, and shouldbe of sufficient weight or amount to keep theintermediate wheel B nearly perpendicular to or nearly directly underthepinion O, and prevent its being carried too far upward on the rim 1)when in operation.

"it are guides or rods secured to the inner side of the rim b, for thepurpose of guiding the wheel B and keeping it in position.

The pinion O is fixed on and secured to the shaft F, which runs and hasbearings within the hollow shafts 1) D of the outer annular wheel A, andthe teeth of the said pinion mesh with those of the wheel B, as plainlyshown in the drawings.

The driving-power is applied to the shaft F of the pinion O, which,being set in motion, imparts a rolling motion to'the intermediatewheelB, and causes it to ascend a short distance on the rim 7: of the outerwheel A, which is thus put in motion, as the weight of the intermediatewheel, loaded as before described, is brought to bear thereon.

.The pecul'ar fe. tures of this invention are,that the comparativelysmall amount of power requisite to give a rolling motion to the loadedintermediate wheel,

places the latter in a position in which its weight acts 7 upon the rimof the outer annular wheel, and drives the same.

The wheel A may, if desired, be provided with teeth on the inner side ofits rim i), so as to zeauwith the intermediate wheel B, in which casethe flanges d d would be left off. But we consider the constructionabove described as being preferable.

We may herestate that the mechanism herein described has beenpractically tested by attaching the same to the machinery of a saw-milldn'ven by steam power, when it was found that by its use, as anauxiliary, the engine could more easily accomplish the work with fortypounds pressure of steam than it had previously done with eighty poundspressure of steam.

In this instance, the weight of the intermediate wheel was-abouttwenty-four hundred pounds, the diameter of the pinion was twenty-twoinches, that of the intermediate wheelwas thirty-three inches, and theminor diameter of outer annular wheel was eighty eight inches.

Having thus described our invention,

What we claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. A weighted or loaded wheel, B, supported on the inner surface of therim of an outer annular wheel A, and operating upon and in connectionwith the same, whether the inner surface of the rim of the said wheel Ais provided with teeth or with a plain friction-surface, substantiallyas herein shown and described and for the purposes set forth.

2. The pinion-wheel 0 upon the shaft F, the latter running within thehollow shafts D D of the outer wheel A, in combination with the loadedintermediate wheel B, and said outer annular wheel A, all operating asherein shown and described, and substantially for the purposes setforth.
